The Bretons were not always such strong allies of the English. In the early part of their existence especially they fought against the English, and gradually fell under French influence.
However, in 1341, Jean IV de Montford decided to contest the rights of his niece Joanna of Penthièvre and her husband Charles de Blois, a favourite of the French, to the duchy of Brittany. Jean gained the patronage of the English king Edward III and his support in the following Breton War of Succession.
After the defeat of Charles, Brittany, now under the reign of Jean de Montfort, allied with the English against the French in the Hundred Years' War.
